Fast-Acting Threaded On/Off Valves
Push a button or flip a toggle switch to start or stop flow. Often used in testing and sampling, these valves are useful when you need to dispense a small amount of liquid.
Nickel-plated brass valves resist corrosion better than plain brass valves.
Toggle valves stay open until you flip them closed. Since they don't need to be held open, they’re often used to dispense larger samples than push-button valves. You can see if these valves are open or not based on the toggle's position.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Fast-Acting Panel-Mount Threaded On/Off Valves
Start or stop flow with the flip of a toggle switch or the push of a button. These valves are often used in testing and sampling applications where you need to dispense a small amount of liquid. They fit through a cutout, so the body of the valve stays safe inside your instrumentation panel.
Nickel-plated brass valves resist corrosion better than plain brass valves. 316 stainless steel valves stand up to corrosion better than both plain and nickel-plated brass valves.
Manual-return valves stay open until you flip the toggle off. Since they don't need to be held open, they’re often used to dispense larger samples than spring-return valves. It’s also easy to check if these valves are open or not based on the toggle’s position. Spring-return valves automatically close when you release the toggle or push button. They’re ideal for intermittent use and precise flow control to prevent spills.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Swivel Threaded On/Off Valves
Make connections from any direction—the body of these valves swivels 360° for easy installation. Often used in testing and sampling applications, they quickly open and close with a toggle or button.
Toggle-switch valves stay open until you flip them closed. Since they don’t need to be held open, they’re often used to dispense large samples. The toggle’s position shows you if they’re open or closed.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Fast-Acting Panel-Mount On/Off Valves with Yor-Lok Fittings
- Valve Type: Stem
- For Use With: Air, Argon, Helium, Krypton, Neon, Oil, Water, Xenon
- Seal Material: PTFE Plastic
Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels. For extra gripping power and a strong seal, they have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.
316 stainless steel valves are more corrosion resistant than brass valves.

On/Off Valves with Garden Hose Threads
Start and stop the flow of water through your garden hose.
Plastic valves are lighter in weight than metal valves, but they’re typically not as durable. TPR-coated valves stay safe to touch because they won’t get too hot in the summer or too cold in the winter.
Valves with a toggle switch are easy to use one-handed because you can flip the water on or off with just your thumb. Add kink absorbers to eliminate sharp bends between your hose and your valve, maximizing flow and preventing damage.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Wye-Shaped On/Off Valves with Garden Hose Threads
Convert one faucet into two, four, or five outlets.
All valves have shut-off outlets, so you can start and stop the flow to outlets individually. You can also use the shut-off to release pressure or drain residual water after disconnecting hose. Plastic valves are lighter in weight than metal valves, but they’re not as durable. Toggle-switch handles easily flick on and off like a light switch.
Valves with TPR coating protect your hands by keeping the valve’s surface from getting too hot or cold.
